I believe that is AGP. If you're just going to be surfing the net and such, just get a GeForce MX 4000 or something really cheap. You could even go w/ a ATI Radeon 9250SE.
I would get a geforce fx 5200. A 64-bit one will be fine no reason to spend extra for a 128-bit one if you not gaming. This way you have full direct x 9 support just in case you ever need it. Plus they dont cost much more then the mx400.
yeah if you really wanna cut costs get a chep m/b with integrated graphics. my suggestion though is same as first post though. get a GeForce MX 4000. speaking of which i saw one for $10 australian the other day. this shop gave me an ATX tower with working PSU for free!!! no catches i swear to god. he just gave it to me and i didnt even buy anything, so it does actually pay to visit a real shop every now and then
